For those not aware, FFG cycles out the tournament legality of each cycle/expansion in its LCG's. Their current strategy is to try to maintain legality of expansion cards for 3-4 years. Here's the FFG article about rotation . I think for most of their LCGs that is around 1500 legal cards at max. In Netrunner, the Core Set and Deluxe Boxes are always legal, it's just the small expansion packs that cycle out. Obviously this means balance it's most critical on the Core and Deluxe boxes. Personally, I'd like rotation to be 18-24 months as I think 3-4 years is too long and too many cards to balance (I know others will disagree). I just like to keep the game fresher and minimize the number of errata / ad-hoc penalized cards in play. Anyway, I wanted to increase awareness for this for those not familiar with LCG rotations and I think it's probably something that can still change as the game hasn't even come out yet.
What's your views on optimum rotation schedules?
